There are five Google Groups mailing lists that are related to CHILDES and TalkBank issues.
To subscribe to these lists, you can click on the links given below for each group.
However, when you do this for the first time, you will be asked to set up a Google Groups account.
This is not a full Gmail account and they only ask for your name and password.
After you do that, when you later log on you can go directly to the relevant list and subscribe by
selecting "edit my membership" which is an option in the middle of the column on the right of the page.
When you subscribe, it is important to also provide

a one-sentence statement about your research interests.

This is necessary to make sure that the subscription request is not coming from a spam operation.
